The following counts were made, respectively: Dorsal rays I, 7 

 (I, 7; I, 7; I, 7); anal I, 3 (I, 4; I, 4; I, 4); pectoral always I, 6 and 

 pelvic always I, 5; number of scutes in lower lateral series 24 (24; 

 23 ; 24) ; plates from dorsal origin to adipose 5 (5 ; 5 ; 5) ; plates from 

 base of anal to base of midcaudal fin rays 12 (12; 11; 12); plates 

 in front of dorsal fin 4 (4; 4; 4); spines on interopercle 16 (17; 14; 

 9 and 12); number of tentacles at corner of mouth plus marginal 

 series plus those at corner of mouth 6 + 8 + 6 (5 + 8+6; 4 + 9 + 5; 

 3 + 7 + 3); for additional counts see table 18. 



Head depressed, snout with the anterior portion fleshy, this area 

 much wider in males tlian in females ; the dermal cirri on adult males 

 multifid, especially those in the Y-shaped group near the middorsal 

 line; the marginal series of cirri developed in females; the preopercular 

 spines are hooked and contained l}i to 2 times in the interorbital 

 space; the three plates behind the supraoccipital are not divided in 

 the center; depressed dorsal fin reaches a little beyond the base of 

 the long spine of adipose fin; none of the plates keeled; belly naked; 

 breast naked; teeth small, very numerous and bifid; lips papillate; a 

 smaU barbel at the corners of the mouth; pectoral spines reach to 

 opposite end of first third of pelvic spine; caudal fin on young a little 

 concave, but in adults somewhat convex, the lower lobe longest; 

 posterior margin of dorsal a little convex. 



Color. — When alive this species was dark brown to blackish and 

 covered with dull-yellow or light-brown spots; the tips of the rays of 

 the upper and lower lobes of the caudal fin were yellowish orange, as 

 were the tips of the first rays of the dorsal fin. Body and head
